Specifying admin password.
The admin password is very important, not only can it protect the main program of Password Door to prevent unwanted users from changing the settings you have made, but also it can protect the uninstaller so that none can uninstall the software without the admin password. The admin password also is a master password that can be used to allow any protected program.
Password Door will prompt you to specify the admin password when you install the software. You must set an admin password or the setup will not continue to the next step. You can change the admin password at any time by clicking the Change Admin Password... in the Options page.
Protecting a program.
It's so easy to protect a program: You can just double-click at any item in the Installed Programs to protect it. Password Door provides several methods for you to protect any program on your computer.
Password Door automatically search all the installed programs on your computer, and list them in the main window. You can just double-click at any item in the Installed Programs, to protect the item.

You can click the Browse
icon to browse your computer and select any program to get it to be protected.
You can drag the Target
icon to the main window of any program to get the program protected.
Note: You can set an individual password for each protected program, by clicking the Change... button in the Program Information dialog box. If you do not set password to a program, then the admin password can be used to allow the protected program.
Disabling protection for an individual program or all programs temporarily.
You can disable the protection for any program you have protected. Select the program in the Protected Programs, then click Disable. The protection will be disabled until you choose the same program and click Enable to enable it again.
Clicking Deactivate in the Options page will disable the protection for all programs. You can click Activate to enable the protection again. Note the protection will be automatically enabled after computer rebooted.
Using advanced features.
Password Door provides advanced features to help you to protect some programsthat can not be protected with the normal method.
The Enable EXE Identity by default will be selected, Password Door can protect most programs by using that feature. You needn't, and it's not recommended, to disable that option.
You can use the Class Name & Title to protect any program or even a set of programs. For example: Set the Window Title to be "zip" then all programs that the main window contains the string 'zip' will be protected.

Using schedule features.
Schedule features can be used to protect any program daily, weekly, monthly or at any time you specified. Note that the feature depends on the system date time, so you should prevent users from changing the system time if you plan to use the schedule options. (You can prevent users from changing system time by modifying the system security policy)
